Actualización de las técnicas para el tratamiento de las recesiones periodontales / Update of techniques for the treatment of periodontal recessions

RESUMEN Introducción: A lo largo de los años se ha propuesto una notable variedad de protocolos quirúrgicos periodontales, cuyo enfoque pasó de la simple resolución de defectos de tejidos blandos a la realización de procedimientos predecibles y mínimamente invasivos. Inicialmente se usaba el injerto gingival libre. Posteriormente se han probado diversas técnicas, incluidas aquellas con sustitutos de tejidos blandos, como membranas tipo Alloderm. Hoy en día se considera el gold standard el injerto de tejido conectivo subepitelial asociado al colgajo de avance coronal. Por último, se ha examinado la técnica Pinhole, con mayor preservación de tejido y resultado más estético. Objetivos: El objetivo de esta revisión fue la comparación de técnicas actualizadas para el tratamiento de recesiones múltiples en maxilar superior e inferior. El resultado del procedimiento se evaluó en términos de cobertura radicular completa, reducción de la recesión, ganancia en altura y volumen, resultado estético, dolor postoperatorio y morbilidad del lecho donante y receptor del paciente. Material y métodos: Se realizaron búsquedas electrónicas y manuales para recopilar estudios de boca dividida, ensayos clínicos controlados aleatorios, series de casos, estudios piloto, libros de periodoncia, estudios de casos, revisiones sistemáticas y metanálisis, incluyendo los defectos de recesiónes gingivales múltiples, en maxilar y mandibular, de las cuatro clases de Miller, debido a su extensa evidencia. Resultados: Se incluyeron treinta y cuatro publicaciones y se extrajeron datos sobre el resultado de las técnicas quirúrgicas de dieciocho artículos. La evaluación clínica analizó la cantidad de cobertura radicular completa, la reducción de la recesión y la ganancia de altura y volumen, mientras que la perspectiva del paciente se expresó en términos de satisfacción estética y posibles complicaciones postoperatorias. Los procedimientos de los últimos diez años mostraron mejores resultados en todos los factores mencionados anteriormente. Conclusión: La predictibilidad y la estabilidad del tratamiento a largo plazo representan los factores que guían el proceso de elección de la técnica y que añaden valor a los procedimientos más actualizados. Se observaron progresos tanto a nivel estético, al reducir las discrepancias entre el área intervenida y el tejido circundante, como a nivel postoperatorio, al aminorar las molestias del paciente. Los desafíos propios de esta rama pronto podrían encontrar respuesta gracias a su rápida evolución, la cual permite concebir más avances.

ABSTRACT Background: Along the years, a remarkable variety of periodontal surgical protocols has been proposed, the focus of which has shifted from the mere resolution of a soft tissue defect to the performance of predictable and minimally invasive procedures. Initially, the free gingival graft was used. Subsequently, many different techniques were experimented, including those using soft tissue substitutes, such as the Alloderm membrane. Nowadays, the association of the connective tissue graft with the coronally advanced flap is considered the gold standard. Finally, the Pinhole technique, being a more conservative method in terms of tissue preservation and aesthetic outcome, was proposed. Objectives: The aim of this review was the comparison of the updated techniques for the treatment of multiple periodontal recessions, affecting both maxilla and mandible. The procedure outcome was assessed in terms of complete root coverage, recession reduction, gain in height and volume, aesthetic outcome, patient's post-operative pain and morbidity of donor and recipient sites. Material and methods: Electronic and hand searches were performed to collect split- mouth studies, randomized controlled clinical trials, case series, pilot studies, periodontal books, case studies, systematic reviews and meta-analysis, including maxillary and mandibular multiple gingival recession defects of all four Miller's classes, for its extensive evidence. Results: Thirty-four publications were included and data regarding the surgical techniques outcome were extracted from eighteen articles. The clinical evaluation analyzed the amount of complete root coverage, recession reduction and gain in height and volume, while the patient's perspective was expressed in terms of aesthetic satisfaction and possible postoperative complications. Procedures in the last ten years showed better results in all the above-mentioned factors. Conclusion: Procedural predictability and long-lasting treatment stability embody the factors driving the technique election process and adding value to more updated procedures. Progress was observed both at an aesthetic level, by reducing the discrepancias between the surgical region and the surrounding tissue, and at a postoperative level, by reducing patient discomfort. The challenges inherent to this branch could soon find answers thanks to its prompt evolution, which allows for further advances to be conceived.

Recubrimiento radicular de recesiones gingivales con matriz dérmica acelular / Root coverage of gingival recession with acellular dermal matrix

La recesión gingival es considerada como una deformidad o condición mucogingival, la Academia Americana de Periodontología, define a la recesión gingival como el desplazamiento del margen del tejido blando apical a la unión cemento-esmalte con la exposición de la superficie radicular. El tratamiento de las recesiones gingivales es un motivo de consulta común debido a razones estéticas, hipersensibilidad dentinaria, molestias durante el cepillado e incluso temor a la pérdida dentaria. Es una situación clínica común, 60% de la población humana tiene algún tipo de recesión gingival. Al realizar el examen clínico a paciente masculino de 55 años, se observó una recesión gingival tipo 1 (RT1) sin pérdida de inserción interproximal de la clasificación de Cairo. Se realizó el colgajo posicionado coronalmente (CPC) utilizando una matriz dérmica acelular (MDA) de origen humano OrACELL®. Se obtuvo resultado favorable en el recubrimiento de recesiones gingivales múltiples; considerándolos como una buena alternativa frente a los injertos gingivales autógenos. Concluyendo que, el uso de la matriz dérmica acelular para el tratamiento de la recesión gingival tipo 1 es una adecuada opción para el recubrimiento radicular. Se recomiendan más estudios a largo plazo para ver la estabilidad de los resultados obtenidos con la MDA (AU)

Gingival recession, considered a deformity or mucogingival condition, the American Academy of Periodontology, defines gingival recession as the exposure of the root surface resulting from migration of the gingival margin apical to the cementoenamel junction (CEJ). The treatment of gingival recessions is a common reason for consultation due to aesthetic reasons, dentin hypersensitivity, discomfort during brushing and even fear of tooth loss. It is a common clinical situation, 60% of the human population has some kind of gingival recession. Clinical examination of a 55-year-old male patient showed a type 1 gingival recession (RT1) without loss of interproximal insertion of the Cairo classification. Coronally advanced flap (CAF) was performed using an acellular dermal matrix (ADM) of human origin OrACELL®. Favorable results were obtained in the coating of multiple gingival recessions; considering them as a good alternative to autogenous gingival grafts. Concluding that, the use of the acellular dermal matrix for the treatment of gingival recession type 1, is a suitable option for root lining. Further long-term studies are recommended to see the elasticity of MDA outcomes (AU)

Colgajo de reposición coronal, con y sin injerto de tejido conectivo, para tratar recesiones gingivales / Coronally repositioned flap with and without connective tissue graft to treat gingival recession

Introducción: Las recesiones gingivales son afecciones de las encías, que son muy frecuentes y podrían provocar repercusiones estéticas, hipersensibilidad dentinaria y tener más tendencia a la formación de lesiones cervicales. Es necesario recubrir la superficie radicular mediante técnicas regenerativas periodontales. Objetivo: Comparar la cantidad de recubrimiento radicular, la profundidad al sondaje y el nivel de inserción clínica, empleando las técnicas de colgajo de reposición coronal, con y sin injerto de tejido conectivo, en pacientes con recesiones gingivales Miller I y II. Métodos: Se incluyeron un total de 16 pacientes con recesiones gingivales Miller clase I y II, de los cuales se seleccionaron 50 piezas dentarias tratadas quirúrgicamente para cubrir las recesiones. Se utilizaron las técnicas de colgajo de reposición coronal, con y sin injerto de tejido conectivo. Las mediciones clínicas fueron comparadas al inicio y a los tres meses posoperatorios. Resultados: Al tercer mes poscirugía los resultados del recubrimiento radicular, profundidad al sondaje y el nivel de inserción clínica para la técnica colgajo de reposición coronal con injerto de tejido conectivo, fueron 0,96 ± 1,33; 0,87 ± 0,63; 1,83 ± 1,7 y para la técnica colgajo de reposición coronal fueron 1,44 ± 1,19; 1,04 ± 0,52; 2,48 ± 1,48, respectivamente. Al comparar el recubrimiento radicular intergrupo no se encontraron diferencias significativas (p = 0,11). Sin embargo, al comparar la profundidad al sondaje intergrupo (p = 0,04), el nivel de inserción clínica intergrupo (p = 0,001) y todas las mediciones clínicas intragrupo (p = 0,001), se encontraron diferencias significativas. Conclusiones: La técnica de colgajo de reposición coronal, con y sin injerto de tejido conectivo, demostró diferencias significativas en la profundidad al sondaje y el nivel de inserción clínica en recesiones gingivales Miller I y II. No se alcanzaron diferencias significativas para el recubrimiento radicular en ambas técnicas a los 3 meses de seguimiento(AU)

Introduction: Gingival recession is a very common gum condition which may result in aesthetic alterations and dentin hypersensitivity, and increase the probability of cervical lesions. It is necessary to cover the root surface using periodontal regeneration techniques. Objective: Compare the amount of root coverage, probing depth and clinical insertion level, using coronally repositioned flap techniques with and without connective tissue graft in patients with Miller I and II gingival recessions. Methods: A total 16 patients with Miller class I and II gingival recessions were included in the study, from whom 50 teeth were selected which had been treated surgically to cover the recessions. The techniques used were coronally repositioned flap with and without connective tissue graft. Clinical measurements were compared at the start of the postoperative period and three months later. Results: Three months after surgery, root coverage, probing depth and clinical insertion level were 0.96 ± 1.33; 0.87 ± 0.63; 1.83 ± 1.7, respectively, for coronally repositioned flap with connective tissue graft, and 1.44 ± 1.19; 1.04 ± 0.52; 2.48 ± 1.48, respectively, for coronally repositioned flap. Root coverage intergroup comparison did not find any significant differences (p = 0.11). However, intergroup comparison of probing depth (p = 0.04) and clinical insertion level (p = 0.001), and all the intragroup clinical measurements (p = 0.001) did find significant differences. Conclusions: Coronally repositioned flap technique with and without connective tissue graft showed significant differences in terms of probing depth and clinical insertion level in Miller I and II gingival recessions. At three months' follow-up, no root coverage significant differences were observed for either technique(AU)

Rethinking the decision-making process to treat gingival recession associated with non-carious cervical lesions.

The presence of a tooth-surface defect, such as a non-carious cervical lesion (NCCL), associated with sites of gingival recession (GR) defects creates a combined soft tissue/tooth defect (CD) that requires a different treatment plan. This study aimed to critically review the literature regarding the available treatment protocols for CDs and suggest a new decision-making process. NCCLs were classified as Class A-: the cementoenamel junction (CEJ) was visible and the root surface discrepancy was < 0.5 mm (no step); Class A+: CEJ was visible and the root surface discrepancy was > 0.5 mm (with a step); Class B-: unidentifiable CEJ without a step; Class B+: unidentifiable CEJ with a step. NCCLs affecting both root and crown surfaces (Class B) lead to CEJ destruction and consequently eliminate an important landmark used before and after root coverage procedures. The depth of the root surface discrepancy is vital owing to its possible impact on soft tissue adaptation after healing, which, in turn, may influence the treatment options, namely the use of graft and/or composites to compensate for the discrepancy. Clinically, a step with horizontal depth greater than 0.5 mm should be recognized as the minimum threshold value to define this condition. Extremely deep defects tend to assume a V-shaped topography. Therefore, extremely deep V-shaped defects were classified into subclasses A+V, a V-shaped defect, and B+V, a V-shaped defect with loss of CEJ, for management considerations. The treatment options, supported by the literature, and a decision-making process to deal with each condition are presented.

Use of cyanoacrylate for the stabilization of tissues in root coverage procedures: A case series report with 5 years follow up

ABSTRACT: A variety of periodontal plastic surgery techniques have been proposed to correct aesthetic and functional problems caused by gingival recession, with root coverage using connective tissue grafts being the one most commonly performed. These surgeries, however, are partially dependent on tissue graft stability. In this case series, we describe the use of a tissue adhesive (cyanoacrylate) as a solution for graft stabilization. Two patients with Cairo's type 1 gingival recession were treated with an envelope technique using connective tissue graft stabilized with cyanoacrylate alone. The results were a faster procedure and complete root coverage, even after 5 years of follow-up. Our findings suggest that cyanoacrylates can be an alternative to standard graft stabilizing procedures, leading to a stable root coverage in RT1 recessions.

Association between platelet-rich fibrin and collagen matrix for root coverage: Case Series

ABSTRACT: The aim of this case series was to evaluate the effectiveness of the collagen matrix (CM) associated with platelet-rich fibrin (PRF) in the treatment of gingival recession (GR). Six non-smoker patients that presented at least one site with single GR in the maxilla were included. Four GR were treated with conventional coronally advanced flap and six GR were treated with a modified coronally advanced tunnel technique. In both techniques, the PRF was immobilized above the CM. A reduction in the GR depth (2.00 mm (1.50-3.50) to 0.00 (0.00-0.00)) and pocket probing depth (1.25 mm (1.00-2.00) to 1.00 mm (1.00-1.62)) resulting in complete root coverage in all GR after 1 month. However, a displacement of the marginal gingival of 0.50 (0.00-1.00) associated with a gingival thickness reduction (1.35 (0.90-1.82)) was observed after 12 months. The association of the CM and PRF was effective in the GR coverage.

Estética en periodoncia: integrando la microcirugía plástica periodontal y las cerámicas adheridas / Esthetics in periodontics: integrating periodontal plastic surgery and bonded ceramics

La percepción hacia el alcance de la excelencia estética se traduce especialmente en saber interpretar y satisfacer los deseos del paciente, empleándose para eso, todos los conocimientos disponibles en la literatura científica. La utilización de carillas, coronas cerámicas o de Circonio pueden representar un tratamiento, predecible y confiable, cuando las condiciones, básicas de salud se encuentran ya resueltas. Una de estas condiciones, se refiere a un marco de salud Periodontal, con contornos gingivales estéticos y naturales. En algunos casos, donde esto no sucede, la microcirugía estética puede ser un recurso práctico y predecible. A su vez la evidencia científica nos ofrece parámetros para guiarnos y así alcanzar un correcto diagnóstico, planeamiento seguro, técnica adecuada y la utilización del material más indicado para cada situación clínica. La subjetividad estética puede estar escondida entre líneas en la ciencia. Con ésta recopilación acompañado con la ejemplificación de los casos clínicos desarrollados, intentaremos aproximarnos a la excelencia (AU)

Treatment of peri-implant soft tissue defects: a narrative review.

Soft tissue defects around dental implants, such as papilla or volume loss, peri-implant recession and alterations of the ridge color and/or texture, lead to esthetic and functional complaints. Treatments of these defects in implants are more demanding than in teeth because peri-implant tissue exhibits different anatomical and histological characteristics. This narrative review discusses the proposed treatments for soft tissue defects around implants in the current literature. Several clinical and pre-clinical studies addressed methods to augment the quantity of the peri-implant keratinized mucosa. Autogenous grafts performed better than soft tissue substitutes in the treatment of soft tissue defects, but there is no clinical consensus on the more appropriate donor area for connective tissue grafts. Treatment for facial volume loss, alterations on the mucosa color or texture and shallow peri-implant recessions are more predictable than deep recessions and sites that present loss of papilla. Correction of peri-implant soft tissue defects may be challenging, especially in areas that exhibit larger defects and interproximal loss. Therefore, the regeneration of soft and hard tissues during implant treatment is important to prevent the occurrence of these alterations.

Long-Term Outcome (10 Years) of Multiple Recession-Type Defects Treated With Acellular Dermal Matrix Graft and Coronally Advanced Flap: A Case Report.

INTRODUCTION: There is limited evidence related to the long-term treatment outcomes of acellular dermal matrix graft (ADMG) plus coronally advanced flap (CAF) for the treatment of multiple recession defects. The aim of this case report is to assess the short- and long-term clinical outcomes of Miller Class I multiple gingival recession-type defects in the maxilla treated with ADMG plus CAF. CASE PRESENTATION: A 36-year-old female patient smoking < five cigarettes per day presented multiple adjacent Miller Class I gingival recession in the left maxilla and was referred for treatment with chief complaints of dental hypersensitivity and esthetics. Root coverage was achieved by ADMG + CAF and the patient underwent a 10-year follow-up. CONCLUSIONS: Within the limits of this case report, mean root coverage obtained at 6 months could not be maintained in the long term. A significant relapse was detected after 10 years, from 80% complete root coverage (CRC) at 6 months to 40% at 10 years. Monitoring, compliance, and reinstructions in oral hygiene techniques seem mandatory for minimizing relapse of gingival recessions after root coverage procedures.

Manejo de tejidos blandos en implantes con carga inmediata del sector anterosuperior: reporte de caso clínico / Handling of soft tissues of an immediate loading implant on the upper anterior sector: report of a clinical case

Los implantes dentales se han colocado en sitios de extracción cicatrizados mediante un procedimiento quirúrgico en dos etapas para un periodo de tres a seis meses sin carga. Sin embargo, los pacientes esperan ser rehabilitados lo antes posible, especialmente los pacientes sometidos a restauraciones estéticas en el maxilar anterior. Después de la colocación del implante, la fabricación de la restauración temporal y la carga del implante dentro de las 48 horas se denominan carga inmediata. Esto acorta el tiempo del tratamiento, ya que requiere menos intervenciones quirúrgicas, reduce la pérdida ósea crestal periimplantaria, conduce a la preservación de la morfología de los tejidos blandos y mejora la estética. En este artículo se hablará del caso clínico de un paciente femenino de 44 años de edad que presentaba pérdida del órgano dentario 21. Se realizó valoración periodontal, radiográfica y tomográfica de este órgano dentario, se colocó implante con la utilización de guía quirúrgica y protésica acrílica termocurable, se realizó carga inmediata, el provisional fue conformado con contorno subgingival cóncavo y se toman en cuenta criterios de contorno crítico y subcrítico para el desarrollo ideal del perfil de emergencia. En las citas de valoración se encontraron los tejidos periimplantales estables y la paciente no refirió sintomatología (AU)

Dental implants have been placed in scarred extraction sites by a twostage surgical procedure for a period of three to six months without load. However, patients expect to be rehabilitated as soon as possible, especially patients undergoing esthetic restorations in the anterior maxilla. After implant placement, the fabrication of the temporary restoration and implant loading within 48 hours are called immediate loading. This shortens the time of treatment, beacause it requires fewer surgical interventions, reduces peri-implant crestal bone loss, leads to the preservation of soft tissue morphology and improves aesthetics. In this article we will discuss the clinical case of a 44-year-old female patient who had lost the dental organ 21. Periodontal, radiographic and tomographic assessment of this dental organ was performed, an implant was placed with the use of surgical guide and acrylic prosthesis thermocurable, immediate loading was performed, the provisional was formed with a concave subgingival contour and critical and subcritical contour criteria were taken into account for the ideal development of the emergence profile. In the assessment appointments stable periimplant tissues were found and the patient did not report symptoms (AU)

Treatment of peri-implant soft tissue defects: a narrative review

Abstract Soft tissue defects around dental implants, such as papilla or volume loss, peri-implant recession and alterations of the ridge color and/or texture, lead to esthetic and functional complaints. Treatments of these defects in implants are more demanding than in teeth because peri-implant tissue exhibits different anatomical and histological characteristics. This narrative review discusses the proposed treatments for soft tissue defects around implants in the current literature. Several clinical and pre-clinical studies addressed methods to augment the quantity of the peri-implant keratinized mucosa. Autogenous grafts performed better than soft tissue substitutes in the treatment of soft tissue defects, but there is no clinical consensus on the more appropriate donor area for connective tissue grafts. Treatment for facial volume loss, alterations on the mucosa color or texture and shallow peri-implant recessions are more predictable than deep recessions and sites that present loss of papilla. Correction of peri-implant soft tissue defects may be challenging, especially in areas that exhibit larger defects and interproximal loss. Therefore, the regeneration of soft and hard tissues during implant treatment is important to prevent the occurrence of these alterations.

The effects of different restorative materials on periodontopathogens in combined restorative-periodontal treatment.

Objective The aim of the study was to evaluate the association between subgingival restorations and the target periodontopathogenic bacteria (Pg, Td and Pi) in subgingival biofilm during one year after combined restorative-periodontal treatment. Material and Methods Seventeen systemically healthy subjects, who were positive for the presence of three cervical lesions associated with gingival recessions in three different adjacent teeth, were included in the study. A total of 51 combined defects were treated with connective tissue graft plus a nanofilled composite resin (NCR+CTG), a resin-modified glass ionemer cement (RMGI+CTG) and a fluoride-releasing resin material with pre-reacted glass (PRG), called giomer (Giomer+CTG). Periodontal clinical measurements and subgingival plaque samples were obtained from all combined defects at baseline and at 6 and 12 months after the surgery. The number of bacteria were evaluated by the real-time polymerase chain reaction (qPCR) method. Results No statistically significant difference in the amount of DNA copies of Pg, Td and Pi was observed in any of the groups at any time points (p>0.05). In addition, there was no statistically significant difference in the amount of DNA copies of the bacteria at baseline and at 6 and 12 months postoperatively, regardless of treatment group (p>0.05). Conclusion This study suggests that subgingivally placed NCR, RMGI and giomer restorations can show similar effects on periodontopathogenic bacteria in the treatment of gingival recessions that are associated with noncarious cervical lesions (NCCLs).

O uso da matriz colágena porcina na reconstrução tecidual em Periodontia / The use of the porcin collagen matrix in the periodontal tissue reconstruction

A doença periodontal causa uma perda na estrutura de suporte dos elementos dentários. Como consequência, ocorre o aparecimento de sequelas provenientes dessa doença. Por conta disso foram desenvolvidos materiais com a fi nalidade de regeneração tecidual na estrutura de suporte, para que houvesse maior sobrevida desses elementos, aumento na quantidade de gengiva inserida e melhor otimização estética para os pacientes. Dentre os inúmeros materiais, temos a Matriz Colágena Porcina, que simplesmente é uma membrana obtida a partir de suínos, sendo que esta passa por uma cadeia de procedimentos, com a fi nalidade de minimizar e/ou eliminar qualquer tipo de interação alergênica no ser humano. A sua utilização é dada principalmente no aumento de tecidos moles ao redor de dentes afetados com a doença periodontal e em implantes osseointegrados, trazendo como principal vantagem a redução de morbidade do paciente, evitando, assim, a necessidade de um segundo sítio cirúrgico.

Periodontal disease results in the loss of structural support on dental elements. As such, sequels can be seen in the mouth. For this, materials were develop for tissue regeneration in order to increase the amount of attached gingiva and to optimize patient esthetics. The porcine collagen matrix is a product were the collagen undergoes a series of several treatments to minimize any type of allergic reaction to the human body. For example, it can be used for soft tissue augmentation around affected teeth and dental implants. Also, the porcine collagen matrix can reduce patient morbidity because it avoids autologous soft tissue harvesting.

Previsibilidade em resolução estética para recessões gengivais / Predictability in esthetic solutions for gingival recessions: a case report

A recessão gengival é uma queixa relativamente comum entre os pacientes quando procuram o cirurgião-dentista, e os motivos desse incômodo são sensibilidade e estética. Os autores relatam que o tratamento de recessões gengivais posteriores bilaterais são realizados a partir do transplante do tecido conjuntivo subepitelial. Já a técnica operatória utilizada nesse caso, para o posicionamento do tecido conjuntivo, foi a de Langer, com reposicionamento coronário do retalho. Houve um aumento considerável com relação ao recobrimento radicular, sugerindo um processo de reparação da recessão gengival bilateral, com a interposição do tecido conjuntivo na área receptora. Em relação à praticidade, a técnica de Langer mostra-se mais fácil de ser realizada com relação ao aspecto estético, recobrimento, ganho em altura e espessura. O objetivo desse trabalho é relatar um caso clínico de resolução estética para recessão gengival. A terapia inicial do presente caso consistiu em instruções de higiene oral acompanhado de raspagem dos dentes nos 30 dias anteriores à cirurgia. Os procedimentos cirúrgicos foram feitos seguindo técnica consagrada pela ciência. O enxerto de tecido do palato foi transplantado para a região de recessão, a fim de recobrir as áreas de exposição radicular. O paciente recebeu instruções de cuidados de higiene. Após 14 dias do pós-cirúrgico, realizou-se a remoção dos pontos e uma instrução para higiene permanente do local. O resultado clínico foi uma boa estética para o paciente. Geralmente não possui recidiva mediante cuidados no controle de higiene oral e hábitos.

Gingival recession is a relatively common complaint for patients seeking treatment due to sensitivity and esthetics. The authors report that the treatment of bilateral posterior gingival recessions is performed using the subepithelial connective tissue grafting. The operative technique used in this case was the Langer's method with coronary flap repositioning. There was a considerable increase regarding root coverage, suggesting repair process of the bilateral gingival recession with the interposition of connective tissue in the recipient area. In relation to clinical aspects, the Langer's technique is easier to be performed in relation to the esthetic aspect, coverage, and gains in height and thickness. The purpose of this paper is to report a clinical case to solve the gingival recession. The initial therapy consisted of oral hygiene instructions and root planning 30 days prior to surgery. Afterwards, the surgical procedures were performed accordingly. The graft was harvested from the palate and transplanted to the recession area to cover the areas of root exposure. After 14 days, sutures were removed and oral hygiene instruction was recommended. The clinical results were excellent in terms of esthetics. Generally, no relapse was observed after good oral hygiene and habits.

L-PRF associado ao enxerto gengival livre no "creeping attachment": estudo clínico randomizado / L-PRF associated with free gingival graft in the "creeping attachment": randomized clinical trial

O propósito do presente estudo clínico será avaliar o efeito do tratamento de recessões gengivais classe II de Miller com enxerto gengival livre (EGL), associado a fibrina rica em plaquetas e leucócitos (L-PRF) no "creeping attachement" (CA). 12 pacientes que apresentavam recessões bilaterais classe II de Miller, localizadas em pré-molares inferiores, totalizando 24 sítios, foram divididos aleatoriamente nos Grupo EGL (n=12), é o grupo controle no qual o sitio recebeu o recobrimento radicular com enxerto gengival livre (EGL); e o Grupo EGL/L-PRF (n=12), EGL associado ao L-PRF, estabilização de membrana de L-PRF no leito receptor e sutura do EGL. Para obtenção do L-PRF, foi realizada a coleta de 20 ml de sangue de cada paciente, que foi imediatamente centrifugado a 2700 rpm, por 12 minutos. Realizou a medida do recobrimento radicular o presente no período inicial e após 30 dias de pós-operatório, e foi avaliado a quantidade de CA (90, 180 e 360 dias). Após 360 dias não foi possível observar uma diferença significativa de CA entre os grupos EGL (1.81 ± 0.40) e 1.00 ± 0.70 (EGL/L-PRF ), entretanto ocorreu diferença na quantidade de mucosa queratinizada, gengiva inserida e altura da recessão. EGL e EGL/L-PRF proporcionaram aumento na mucosa queratinizada e migração tecidual em recessões classe II de Miller(AU)

The main objective of the present clinic study will be to evaluate through observation of the root covering, the "creeping attachment" (CA) on Miller class II gingival recession treated with free gingival graft combined with leucocyte and platelet rich-fibrin (PRFL). 12 patients with bilateral Miller Class II gingival recession in lower premolars were recruited. Group FGG (n=12): control group, the site will receive the root coverage with free gingival graft, and Group FGG/L-PRF (n=12): will be performed an association between free gingival graft and L-PRF, the L- PRF membrane stabilized to the receptor region and suturing the EGL. To obtain this platelet concentrate, 20 ml of blood of each patient will be collected and immediately centrifuged at 2700rpm for 12 minutes. The following parameters will be measured: O`Leary plaque index, gingival index, height of gingival recession, recession width, amount of keratinized mucosa, probing depth (PD) and then, the clinical attachment level will be conducted. The measurements will be performed at 30, 90, 180 e 360 days after the surgical procedure. The CA will be measured at 90, 180 and 360 days. Data will be analyzed statistically (p < 0.05) in a specialized computer program (Bioestat 5.0). After 360 days, significant differences were not found between the two groups for CA, however there was a significant difference for keratinized gingiva, gingival height and clinical attachment level. EGL and EGL/L-PRF are equally successful in the creeping attachment gain in gingival recession of Miller class II(AU)

The effects of different restorative materials on periodontopathogens in combined restorative-periodontal treatment

Abstract Objective The aim of the study was to evaluate the association between subgingival restorations and the target periodontopathogenic bacteria (Pg, Td and Pi) in subgingival biofilm during one year after combined restorative-periodontal treatment. Material and Methods Seventeen systemically healthy subjects, who were positive for the presence of three cervical lesions associated with gingival recessions in three different adjacent teeth, were included in the study. A total of 51 combined defects were treated with connective tissue graft plus a nanofilled composite resin (NCR+CTG), a resin-modified glass ionemer cement (RMGI+CTG) and a fluoride-releasing resin material with pre-reacted glass (PRG), called giomer (Giomer+CTG). Periodontal clinical measurements and subgingival plaque samples were obtained from all combined defects at baseline and at 6 and 12 months after the surgery. The number of bacteria were evaluated by the real-time polymerase chain reaction (qPCR) method. Results No statistically significant difference in the amount of DNA copies of Pg, Td and Pi was observed in any of the groups at any time points (p>0.05). In addition, there was no statistically significant difference in the amount of DNA copies of the bacteria at baseline and at 6 and 12 months postoperatively, regardless of treatment group (p>0.05). Conclusion This study suggests that subgingivally placed NCR, RMGI and giomer restorations can show similar effects on periodontopathogenic bacteria in the treatment of gingival recessions that are associated with noncarious cervical lesions (NCCLs).

Enxerto de tecido conjuntivo subepitelial e retalho coronal em recessões gengivais múltiplas / Subepithelial connective tissue graft and coronal fl ap in multiple gingival recessions

Algumas das principais indicações para o recobrimento de superfícies radiculares expostas por recessão gengival compreendem a hipersensibilidade dentinária cervical e o tratamento de defeitos estéticos. Este trabalho descreveu o tratamento de recessão gengival múltipla classe III de Miller em um periodonto delgado, após 36 meses de uma intervenção cirúrgica com enxerto gengival livre. O tratamento cirúrgico periodontal proposto foi o recobrimento radicular por meio de enxerto de tecido conjuntivo subepitelial associado a retalho reposicionado coronalmente na região vestibular dos elementos 31, 41 e 42. Após 90 dias, foi possível observar o recobrimento parcial da recessão, aumento da espessura tecidual e o controle do biofi lme pelo paciente, promovendo maior proteção da região e redução do risco de recidiva das recessões. Diante da resolução do caso clínico apresentado, pôde-se concluir que a técnica do enxerto de tecido conjuntivo subepitelial associado ao retalho reposicionado coronalmente, quando bem indicada e realizada, pode ser empregada com sucesso em áreas de recessões múltiplas e periodonto com espessura reduzida.

Some of the main indications for the root coverage of gingival recessions include cervical dentin hypersensitivity and treatment of aesthetic defects. This manuscript describes the treatment of a Miller's Class III multiple gingival recession 36 months after a free gingival graft surgical procedure. The periodontal surgical treatment proposed was the subepithelial connective tissue graft associated with a coronally repositioned fl ap at vestibular region of elements 31, 41 and 42. After 90 postoperative days, it was possible to observe an increase on tissue thickness and biofi lm control by the patient, promoting a greater protection of the region and reducing the risk of recession recurrence. It can be concluded that the subepithelial connective tissue graft technique associated with the coronal repositioned fl ap, when well indicated and performed, can be successfully used in multiple recessions and periodontal regions with reduced thickness.

A exposição da superfície radicular ­ uma consequência das recessões gengivais ­ pode causar hipersensibilidade dentinária, cárie radicular, discrepâncias de altura da margem gengival e consequentes defeitos estéticos ao paciente. Dentre as diversas opções de tratamento, os procedimentos cirúrgicos são as estratégias mais indicadas para correção desses defeitos gengivais. Para realizar este tipo de correção, é necessário classifi car esses defeitos, principalmente, quanto à perda de tecido interproximal e presença de mucosa ceratinizada apicalmente à margem gengival. Desta forma, o objetivo desse trabalho foi relatar um caso clínico de recobrimento radicular de múltiplas recessões classe I de Miller, utilizando a técnica de Bruno modifi cada, avaliando a redução das recessões gengivais, a reversão do quadro de hipersensibilidade dentinária e a satisfação estética relatada pelo paciente.

Gingival recession is the gingival margin migration related to the cemetum enamel junction. The root surface exposure, an outcome of gingival recession, may cause dentin hipersensibility, root caries, height variance of gingival margins causing aisthetic problems to the patient. Among the various treatment options, surgical procedures are the most suitable strategies for correction of these gingival defects. In order to perform this type of correction, it is necessary to classify these defects specially concerning about interdental tissue loss and presence of keratinized mucosa apically to the gingival margin. Therefore, the aim of this work was to report a clinical case of root coverage Miller Class I multiple recessions, using the modifi ed Bruno technique, evaluating the gingival recession, reversion of dentin hypersensitivity, and the aesthetic satisfaction reported by the patient.

Recessões gengivais associadas a lesões cervicais não cariosas: uma revisão sobre o tratamento multidisciplinar / Gingival recessions associated with non-carious cervical lesions: a review on the multidisciplinary treatment

Frequentemente, as recessões gengivais (RG) estão associadas a lesões cervicais não cariosas (LCNC), defi nidas como a perda de estrutura dentária ao longo da margem gengival do dente, com a distinta característica de presença de tecido duro mineralizado em contraste com o tecido carioso. A partir de um ponto de vista topográfi co, a LCNC pode envolver apenas a coroa do dente (esmalte e/ou dentina coronal) ou somente a superfície radicular (cemento e/ou dentina radicular), ou pode localizar-se tanto na coroa como na raiz exposta. As principais indicações para o tratamento da LCNC são: 1) estética; 2) hipersensibilidade dentinária; 3) desenvolvimento de cáries; 4) acúmulo de biofi lme. Os procedimentos envolvem o tratamento restaurador e/ou cirúrgico, a depender do tipo de LCNC. Quando a LCNC atinge apenas a coroa do dente, o tratamento restaurador é mais indicado, enquanto uma lesão confi nada à raiz pode ser tratada preferencialmente com cirurgia plástica periodontal. Porém, a realidade clínica é geralmente complexa, o que torna o tratamento combinado mais favorável para certos casos. Portanto, o objetivo desse artigo foi realizar uma revisão da literatura concernente ao tratamento de recessões gengivais associadas a lesões cervicais não cariosas.

Often, gingival recessions (GR) are associated with non-carious cervical lesions (NCCL), defi ned as the loss of tooth structure along the gingival margin of the tooth, with the distinctive feature of the presence of mineralized hard tissue, in contrast to the carious tissue. From a topographical point of view, NCCL may involve only the tooth crown (enamel and/or coronal dentin) or only the root surface (cementum and/or radicular dentin) or can be located both in the crown and exposed root. The main indications for the treatment of NCCL are: 1) aesthetic; 2) dentine hypersensitivity; 3) development of caries; 4) biofi lm formation. The procedures involve restorative treatment and/or surgery depending on the type of NCCL. When NCCL is located exclusively at the tooth crown, the restorative treatment is best suited while a lesion located at the root surface should be treated preferably with periodontal plastic surgery. However, clinical reality is often complex, which makes the combination treatment more favorable for some cases. Therefore, the aim of this article is to review the literature concerning the treatment of gingival recession associated with non-carious cervical lesions.
